I opened the pool a week ago and shocked it with Leslies Chlor Brite. Pool was a bit cloudy and had a LOT of earthworm/nightcrawler remains in the bottom. I added 2 chlorine tablets to the skimmer and the next morning I had 0 chlorine but the water was clearing up nicely. The pH was low so I added 6 boxes of Borax and got it to 7.5. I had to leave to go to Indiana for a few days so I added 4 lbs. of Chlor Brite and 4 chlorine tablets to the pool. When I got home yesterday morning 5/16/2018 the pool had 0 chlorine and the pH had dropped to 7.0 and the water looks very clean and clear. I added more Borax, 2 boxes. I took a sample to Leslie's and they tested and confirmed the 0 chlorine level, told me to shock again with 4 lbs of Chlor Brite and just keep adding more chlor brite when the chlorine gets below 1.
Here are the test results from Leslie's yesterday.
FAC 0
TAC 0
Calcium hardness 160 I added hardness increaser after this
CYA 50
TA 140
PH 7.7
Copper 0
Iron 0
TDSolids 0
Phosphates 250 I am currently running some Phos Free thru the filter to reduce this.
So yesterday at 5 pm I added 4 lbs of Chlor Brite shock and at 10 pm I had 0 free chlorine.
I found your site and just ordered a TF100 test kit.
Any ideas on getting the pool to hold the pH and maintain chlorine would be appreciated. I have had this pool for 23 years and have never seen this before.
Hopefully the test kit will arrive soon.Thanks for any help.
